Bird retinas operate under chronic oxygen deprivation, relying on anaerobic energy production. The pecten oculi serves as a metabolic gateway, delivering sugar and removing waste products.
A new consensus statement provides evidence-based guidance for screening, diagnosis, treatment, and return-to-play protocols for female athletes. The updated report includes a first-of-its-kind adolescent model of the Female Athlete Triad, addressing energy deficiency in growing adolescents.
A research team discovered that leucine prevents the degradation of specific mitochondrial proteins, enabling efficient energy production. This mechanism allows cells to adapt to increased energy demands during periods of nutrient abundance.
Researchers have identified a new population of hypothalamic neurons, Crabp1 neurons, that play a critical role in regulating energy expenditure. Silencing these neurons leads to reduced energy expenditure and obesity, while activating them enhances locomotor activity and protects against high-fat diet-induced weight gain.
Dr. Steven B. Heymsfield joins an elite group of scholars recognized for advancing knowledge and transforming their fields. He has authored over 1,300 scientific publications with nearly 79,000 citations, placing him among the top 500 most-cited researchers globally.

A new study reveals that metabolism increases rapidly during infancy, peaking at around one year old. After a gradual decline until the 20s, metabolism levels off and then slows down again after age 60, with older adults requiring fewer calories. The findings suggest that muscle loss and cellular changes contribute to this decline.
